Definitely knew Bridge Over Troubled Water and A Whiter Shade of Pale - had no idea that was his song. I'm reallly surprised you pointed out his voice as not very good, I think it's fantastic. My favorite song was probably the title track. Good recommendation!

A Whiter Shade of Pale is actually a Procol Harum song. They're a British rock band. Willie was just trying to cover it because it was current at the time. Anyone that can appreciate Willie's voice is a winner in my book. To many he is an acquired taste, so I was just warning you. Glad you dug it. That is awesome!
